Garrett McNamara rides largest wave of all time

Big wave surfer Garrett McNamara stomps this 90-foot mega wave off the coast of Portugal. He and fellow big-wave surfers Al Mennie, and Andrew Cotton were surfing off Praia do Norte, and area known for monster waves. McNamara was set up for this one when it rolled in.

For some perspective, it was like surfing a nine-story building. The camera on the front of his board shows the wave cresting and falling toward McNamara like a fleet of dump-trucks. And, yet, he stays upright.
